Engine oil Castrol or MOTUL

About $22 for 5 Qts. of Castrol (you can buy it on Amazon or at Walmart for a decent price). Filter is about $4.00 or more if you buy a premium filter.

I started using motul 10w40 after my apache rtr 180 crossed 50k kms. It gave the old engine required smoothness and the engine feels stress free.

Germany, 320d, 2008, 280000km, Castrol Edge 5w-30. Every 15000km

Castrol high mileage 5w-30 every 3 to 5k

Any other oil I have tried made my lifter tick super loud in cold weather

I use Castrol Edge 0W-40 in my '08 328, N52. Based on used oil analysis from Blackstone Labs, I'm at a 6K mile change interval.

I run X-Cess 5w-40, seems great. Takes a little longer to heat up than 5w-30 but I imagine you’d want the high thermal stability it offers in your location.

The OEM oil filter worked well to keep insolubles low, and after 8,570 miles on this fill of Castrol High Mileage, the 2.8 TBN shows the oil had active additive to spare.

Castrol Europeans 0W40 is my typical go-to but Mobil-1 is great, get whichever is cheaper.

Personally on my half million mile M54 E46 I use Castrol edge high mileage 5W-30 with a ok filter; mobile one or the stp extended life filter as those two typically come with the red o rings which tend to last much longer than the black ones.

I used to run Motul 800, but switched to 710 now. 800 has a higher flash point for high rpm racing, and I was getting carbon buildup from not running the bike hard enough.
